I have searched, I'm tired of looking. All I can find is where to tie into the computer, which I don't want to do. I just want to splice in on the o2 sensor around the motor. I just don't know where to hook it up. I know this has been covered before and I can't find it. Any help would be greatly appreciated.

 

I ran my o2 lead thru the firewall and into the top of the 3 wire lead just before the shielded wire...tap into the wire (don't remember the color wire) (I will look tonight) and tap it there...it is not as accurate as a wide-band o2 sensor but it helps a bit to know how things are running thru one bank.
